Gain Measurement of the Sinarback 54 Digital Camera

Modifications of a Sinarback 54 Digital Camera for Spectral and High-Accuracy Colorimetric Imaging: Simulations and Experiments

Study on Wicking Measurement in Thin Layer Textiles by Processing Digital Images

The purpose of this work is to assess and develop experimental techniques that allowwicking measurement over a wide range of textiles. Various kinds of fabrics, nonwoven layers and anelectro spinning nylon layer were used as the test materials. A syringe is used to drop a 0.02 g spot ofdistilled water on the sample and a digital camera to take pictures simultaneously. When the wickingprocess st...

Methods of Spectral Reflectance Reconstruction for A Sinarback 54 Digital Camera

There is an urgent need to build digital image databases with adequate colorimetric accuracy for museums, achieves and libraries. Traditional colorimetric imaging suffers from the possibilities of metameric problem, while spectral imaging can facilitate accurate tristimulus estimation and possibilities for spectral reconstruction of each pixel. Spectral image archives can be used to render accu...

Displacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)

There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...
